As' shown,

the recesses 2|h correspond. in shape to the end` walls I of theY radiator, theopenings 2li extend through the bodies 2| vso as to receivethe molten metal from the gates Zf; andthe runners 2|k incline upwardly from the upperwalls of said Thus, the molten Y;

openings to the recesses 2lb. metal from the gates Eef will flow upwardly from the openings 2li into therecesses 2Ih to form the end walls I of the radiator.

The header cores 22 are arranged in 2|. As shown, each of the header cores coinprises a plate that substantially correspondsv in area to the plate-like portions 2If of theend cores and having openings "22e registering withthe openings 2li. Preferably each header core `22 has a relatively wide substantially squareshaped opening 22b extending upwardly through its upper edge and is provided upon opposite sides of said opening in one face thereof with `recesses 22c and 22d respectively corresponding in

area tothe iins

1 and 8. The lower ends'22e and 22f respectively of these recesses and the lower edge 22g of the opening 22a are in line, and runners 22h, 221, 22j, 22k,7221 and 22m respectivelyA extend upwardly `from the openings 22E to said aligned edges and

ends

22e, 22f and 22g respectively. Webs 22n and 221J respectively corresponding in area to the openings I5 and slots 22q corresponding in area to the cross sectionv of the side walls 2 are provided along the upright edgesr22r and 22S respec'tively'ofthe recesses 22c and 22d.

The iin cores 23 correspond in Aarea to the header cores 22 and have openings 23e registering with the openings 22a in the header cores. As shown, each nn core 23 has a pair of 'laterally spaced elongatedopenings 231 and 23c extending upwardly rthrough its upper vedge and is provided in one'face thereof upon opposite sides of said openings with recesses 23d, 23e, 23? and 23g respectively corresponding in area to the ns 1, I2, II and 8. Preferably the lower Yends 23h, 23, 23j and 23k respectively,- of these recesses are in line just below the openings 23b and 23C.

Slots

231 and 23m respectively extend downwardly from the lower ends of the-openings 23b and 23C to 'said aligned ends 2313x231, 233 and 23k, while runners 23H, 23p, 23223r and 23s respectively extend upwardly from the openings 23a to thealigned lower ends of said recesses.` Webs 2st corresponding in area to the V openings i5, Yand slots 23 corresponding in Larea to the cross section of `the side wallsl 2 are provided along the uprightl edges 23v and 23W respectively of the recessesV 23d and 23g, while slots 23X corresponding inareapto the cross section of thepartition 6, andan intermediate web 23y correspondingY in area'to one l of the openings I 6 are provided in a'verticalflineV between the recesses 23e and 23f. In this connectionit will be noted that the upper edge portion 23z of the core part intermediate the openings 23b and 23cis reduced in thickness and is provided with vents 23?ix for core gases so as to prevent undue ypressure and distortion while the .metal is owing Within the recesses 23e and 23f.

The fiuidway cores 24 and 25 extend between the end cores 2| and each preferably has a pair of substantially rectangular header portions 24a andan intermediate web portion 24h. As shown, the header portions 24a are received in the openings 22b in the header cores and are provided at approximately the center of their opposed sides with substantially square-shaped prints 24. AVThe web portions 24b are received in the'openings 23b and 23c and merge into the headerportions 24h at the outer sides thereof. The lower edges 24d of the webs are rounded or curved transversely as shown and are held in place vin the openings 23b and 23c by suitable Y `Yvchaplets 24e, while the-upper edges 24f of the two: series, oneupon the inner side of each end core.

webs are AiiatV and are held in place in the openings by'suitable chaplets 24g. VTo permit the escape of core gases, the uidway cores 24 and 25 have vlongitudinally and transversely extending passages 24h and 24j respectively therein, the transverse passages 24j being at opposite ends of the longitudinal passages and extending through the prints 24.

`The header body corps 26 are preferably blocks of substantially rectangular configuration that are located between the header portions 2!!a of the fluidway cores and have recesses 2lia in opposite sides thereof receiving the prints 24C. As shown, each header core 26 has a transverse passage 2Gb extending between the refor strips 21d and 21e that cover the openings 23b and 23 respectively in the iin cores. Projecting downwardly from the end portions 21c of saidl body rare substantially rectangular-shaped por- .tio'ns 21f that iit within the openings 22b in the header cores','while projecting downwardly from the strip'portions 21d and 21e are ribs 21g and 21h `that rit Within the openings 23b and 23c respectively inthe fin cores. To permit the escape of core gases, suitable openings 21j are pro- -vided in .the coverV core at opposite ends thereof `for registration with the vertical Apassages 26C in the header body cores 26.

In the present instance, the sprue cores 20 .and coresY 2|, header cores 22, iin cores 23, fluidway cores 2li and 25, headerbody cores 26 and cover core 21 of the apparatus are dry sand cores. In use, the

cores

20, 2|, 22 and 23 are assembled and clamped in a suitable rack C (see Figure 1). The fluidway Ycores 24 and 25 with the chaplets 24e and 24g thereon are assembled with the header body cores 26 and such subassembly is then placed in the openings 22h and 23b and 23c respectively in the header and iin cores, and finally the cover core 21 is placed upon the steps 21b`of the end cores and upon the upper edges of the header and iin cores. In

vthis connection it will be noted that the lower end 3B and opposite sidesV SI and 32 respectively of certain of the openings 23b and. 23c are engaged by the chaplets 24E, while the opposite sides 3l and 32 and the lower faces of the ribs 2g-chnes "21 and`2lh are engagedby the chaplets 24g.

Thus, the uidway cores 24 and 25 are effectively held in position for the rpouring ofthe molten metal. ,f Y "A After the parts have been assembled as described, the molten *metalY may be poured into eitheror both of the sprues 2lid andwill flow through the gates 2f, openings 2li, 22,23a, 23b and 23C upwardly through the runners Zik, 22h, 221, 22j, 22k, 22l and 22m, 231, 231223,l 23F andr 23s to the recesses 2lb, 22C, 22d, 23d, 23e, 23'y 23, slots 221, 23u and 23X to form theradiator. Thus, it will be apparent'that the 'endfwalls' I `will Ybe formed inthe recesses 2lh-in thefend cores 2l, the sideV walls 2 -will be formed in the :slots 22el and 231l in the header and iin coresf22 and 23 respectively, the headers Y3 and 'i'luidways' 4-and5 will-be formed in the openings 22",v 23b and 23c respectively in the header and incores, vand-the

fins

1, 8, Il and l2 respectively willbe formed in the

recesses

22C, 23d, 22d, 23g, 23 and 23e' respectively in the header and iin cores. The cover core 21 cooperates with the end, header and iin cores 2
